esp32-thinks

esp32-thinks is an open-source personal AI voice assistant firmware for the ESP32-S3 microcontroller. It supports voice activation via wake word or knob, integrates any OpenAI-compatible speech-to-text, chat, and text-to-speech models independently, enables streaming replies sentence-by-sentence, and runs on low-cost hardware with a mic, speaker and display. The device operates offline-first with headless provisioning and no vendor lock-in, allowing users to configure their own AI endpoints via a simple config and rebuild process. It is built on the Meta muse-gadget-sdk with extensive custom patches to support multi-model AI brains and voice interaction.
